Relationship between Troy Maxson and Jim Bono in the play, Fences?

Bono is Troy Maxson's closest friend. They met while in prison and spent fifteen years together locked inside. Troy has been the leader whom Bono has willingly followed. They work together hauling garbage until Troy is promoted to driver That event, combined with Troy's preoccupation with his pregnant mistress, serves to create the first serious discord between the two men in nearly thirty-four years of friendship. Bono is very concerned with Troy's dalliance with another woman and the risk it poses to his friend's marriage. Jim's wife, Lucille, is never seen on stage, but he speaks of her with obvious affection and admiration; she has tamed his wanderlust. Bono's positive relationship with Lucille demonstrates that a man has the ability to change the direction of his life.
